Check this file for fun: http://www.blender.org/bf/composite_image.blend (any compo node could get preview!) - had to ensure the composite data gets fully copied before it executes thread, so editing is not frustrated. - put back node buttons (missing init) - added WM_jobs api call to check for running job, illustrated with red light icon in 'use nodes' button. - added another callback to WM_jobs, to initialize. use this init to ensure you only do it when job really starts. - added an extra notifier option for WM_jobs, to signal finished job (like redraw image view) - fixed file read error, it copied the screen it read, instead of using it. - commented out annoying prints for missing ops in imagewin

Code Style: use "#pragma once" in source directory This replaces header include guards with `#pragma once`. A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`), because they are used in other places. This patch has been generated by P1561 followed by `make format`.

Merge of the PyNodes branch (aka "custom nodes") into trunk. PyNodes opens up the node system in Blender to scripters and adds a number of UI-level improvements. === Dynamic node type registration === Node types can now be added at runtime, using the RNA registration mechanism from python. This enables addons such as render engines to create a complete user interface with nodes. Examples of how such nodes can be defined can be found in my personal wiki docs atm [1] and as a script template in release/scripts/templates_py/custom_nodes.py [2]. === Node group improvements === Each node editor now has a tree history of edited node groups, which allows opening and editing nested node groups. The node editor also supports pinning now, so that different spaces can be used to edit different node groups simultaneously. For more ramblings and rationale see (really old) blog post on code.blender.org [3]. The interface of node groups has been overhauled. Sockets of a node group are no longer displayed in columns on either side, but instead special input/output nodes are used to mirror group sockets inside a node tree. This solves the problem of long node lines in groups and allows more adaptable node layout. Internal sockets can be exposed from a group by either connecting to the extension sockets in input/output nodes (shown as empty circle) or by adding sockets from the node property bar in the "Interface" panel. Further details such as the socket name can also be changed there.

#define NODE_GRID_STEPS 5
True grid snapping for nodes: This snaps nodes to the actual background grid instead of using incremental offset (which is not useful for nodes). Increment snapping has been disabled for nodes to avoid confusion, grid snap is now the default as it seems to be the most wanted and easy to use mode. Absolute grid snapping happens in a somewhat generic function 'applyGridAbsolute', which could also be used for objects and other transforms later on. It is conceptually similar to the 'project' snapping option, in that it calculates a delta vector for each element on top of the overall transform, which places each node on the grid. Node transform now uses the top-left node corner for TransformData->loc. The transform center is still the average of node centers, so that scaling and rotation works nicely. snapGrid*** functions have been renamed to snapGridIncrement*** to distinguish better between incremental and absolute grid snapping.

/* space_node.c */
Cleanup: Store runtime space node variables in a separate struct This commit moves runtime-only variables from the `SpaceNode` DNA struct to a private struct in `node_intern.h`. Before, it was hard to tell which data needed to be saved in files, this should make it more clear. Node that the `edittree` field is basically a runtime variable, since it's set from the `treepath` list on read, but moving it would require some more invasive changes that I don't think are worth it right now. Also, not all of the moved variables were explicitly cleared on read-- `aspect` is set at the start of a redraw, `cursor` is set in a region callback, and `recalc` was used as an update flag.

Fix for #34739 and #35060, avoid ambiguity in compositor viewer nodes. The design changes coming with pynodes for the node editor allow editing multiple node groups or pinning. This is great for working on different node groups without switching between them all the time, but it causes a problem for viewer nodes: these nodes all write to the same Image data by design, causing access conflicts and in some cases memory corruption. This was not a problem before pynodes because the editor would only allow 1 edited node group at any time. With the new flexibility of node editors this restriction is gone. In order to avoid concurrent write access to the viewer image buffer and resolve the ambiguity this patch adds an "active viewer key" to the scene->nodetree (added in bNodeTree instead of Scene due to otherwise circular DNA includes). This key identifies a specific node tree/group instance, which enables the compositor to selectively enable only 1 viewer node. The active viewer key is switched when opening/closing node groups (push/pop on the snode->treepath stack) or when selecting a viewer node. This way only the "last edited" viewer will be active. Eventually it would be nicer if each viewer had its own buffer per node space so one could actually compare viewers without switching. But that is a major redesign of viewer nodes and images, not a quick fix for bcon4 ...

Merge of the PyNodes branch (aka "custom nodes") into trunk. PyNodes opens up the node system in Blender to scripters and adds a number of UI-level improvements. === Dynamic node type registration === Node types can now be added at runtime, using the RNA registration mechanism from python. This enables addons such as render engines to create a complete user interface with nodes. Examples of how such nodes can be defined can be found in my personal wiki docs atm [1] and as a script template in release/scripts/templates_py/custom_nodes.py [2]. === Node group improvements === Each node editor now has a tree history of edited node groups, which allows opening and editing nested node groups. The node editor also supports pinning now, so that different spaces can be used to edit different node groups simultaneously. For more ramblings and rationale see (really old) blog post on code.blender.org [3]. The interface of node groups has been overhauled. Sockets of a node group are no longer displayed in columns on either side, but instead special input/output nodes are used to mirror group sockets inside a node tree. This solves the problem of long node lines in groups and allows more adaptable node layout. Internal sockets can be exposed from a group by either connecting to the extension sockets in input/output nodes (shown as empty circle) or by adding sockets from the node property bar in the "Interface" panel. Further details such as the socket name can also be changed there.

Avoid node tree update tag when changed nodes which are not affecting result This was we don't have re-compo or viewport re-rendering happening when changing nodes which are not connected to the output at all (for example when adding new nodes or changing settings for unconnected nodes). Only basic operations are covered for now. checks could be added to more tools when needed. Currently it's not fully optimal implementation, but seems to work fast enough. Don't see reliable alternative to that -- keeping tag in the node wouldn't work because of the node groups (which are probably already broken, but should be easy to solve with current approach). So guess it's more matter of optimizing path search from a node to output. Before processing forward let's check whether it's indeed something we want and whether the approach is indeed not fully bad.

A number of new features for the node editor in general and the Frame node in particular. For an detailed user-level description of new features see the following blogpost: http://code.blender.org/index.php/2012/05/node-editing-tweaks/ TL;DR: * Frame node gets more usable bounding-box behavior * Node resizing has helpful mouse cursor indicators and works on all borders * Node selection/active colors are themeable independently * Customizable background colors for nodes (useful for frames visual distinction).

void ED_node_sort(struct bNodeTree *ntree);
True grid snapping for nodes: This snaps nodes to the actual background grid instead of using incremental offset (which is not useful for nodes). Increment snapping has been disabled for nodes to avoid confusion, grid snap is now the default as it seems to be the most wanted and easy to use mode. Absolute grid snapping happens in a somewhat generic function 'applyGridAbsolute', which could also be used for objects and other transforms later on. It is conceptually similar to the 'project' snapping option, in that it calculates a delta vector for each element on top of the overall transform, which places each node on the grid. Node transform now uses the top-left node corner for TransformData->loc. The transform center is still the average of node centers, so that scaling and rotation works nicely. snapGrid*** functions have been renamed to snapGridIncrement*** to distinguish better between incremental and absolute grid snapping.

UI * Node buttons can now use the layout engine. a few simple ones are converted. We'll keep this code in C for now, python wouldn't help much here. * For node buttons not using the layout engine, manually computing the button height is not longer needed. * Node inputs are still not RNA wrapped, would be good to have these available as well for keying, but makesrna does not have access to the bNodeTypes.

Geometry Nodes: initial scattering and geometry nodes This is the initial merge from the geometry-nodes branch. Nodes: * Attribute Math * Boolean * Edge Split * Float Compare * Object Info * Point Distribute * Point Instance * Random Attribute * Random Float * Subdivision Surface * Transform * Triangulate It includes the initial evaluation of geometry node groups in the Geometry Nodes modifier. Notes on the Generic attribute access API The API adds an indirection for attribute access. That has the following benefits: * Most code does not have to care about how an attribute is stored internally. This is mainly necessary, because we have to deal with "legacy" attributes such as vertex weights and attributes that are embedded into other structs such as vertex positions. * When reading from an attribute, we generally don't care what domain the attribute is stored on. So we want to abstract away the interpolation that that adapts attributes from one domain to another domain (this is not actually implemented yet). Other possible improvements for later iterations include: * Actually implement interpolation between domains. * Don't use inheritance for the different attribute types. A single class for read access and one for write access might be enough, because we know all the ways in which attributes are stored internally. We don't want more different internal structures in the future. On the contrary, ideally we can consolidate the different storage formats in the future to reduce the need for this indirection. * Remove the need for heap allocations when creating attribute accessors. It includes commits from: * Dalai Felinto * Hans Goudey * Jacques Lucke * Léo Depoix

Fix T76970: Unneccessary update calls viewport Due to recent changes clicks in the node editor would trigger a depsgraph update resulting in too many redraws. This patch limits the updates to when workbench shown in texture mode in any visible screen. There are still cases where too many updates are created. For example when there are a Cycles render viewport and a Workbench texture viewport on the same screen. This fix is meant as a workaround. The actual fix should add a mechanism to the depsgraph and the viewports should check if they need to be redrawn.
